Yes.

If you complain enough, they'll send you them free ;-) Also,
if you pull down OpenDoc, you get SOM, which is based on it,
and you get IDL docs. If anyone needs the IDL spec, I also
have it.

ILU maybe. The benefit of using IDL or ILU is that they are language
*and* platform independent. Also, they both have free programs that
generate JAVA/C++/C stubs. They also have free object instantiation
libraries available. I prefer IDL simply because it's closer to a
standard.

Sure. The important point (which I tried but failed to make 2 years
ago to a group of developers) is that you can wrap OLE in CORBA (a la
OpenDoc), but it's very hard to go the other way!

Right. That's why I brought up the though of specifying a name
resolution API as well (entity management). You need both to do
anything meaningful.

In an ideal world, you don't really need an entity manager,
but it's a little early for such radical concepts yet... another year
or two, and the WWW will evolve as it should, and we'll be set.
